NAME

acl_copy_int - copy an ACL from external to internal representation

LIBRARY

Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS


.In sys/types.h
.In sys/acl.h acl_t acl_copy_int const void *buf_p

DESCRIPTION

The acl_copy_int function copies an exportable, contiguous, persistent form of an ACL, pointed to by buf_p, to the internal representation.
This function may cause memory to be allocated. The caller should free any releasable memory, when the new ACL is no longer required, by calling acl_free(3) with the (void*)acl_t returned by acl_copy_int as an argument.

RETURN VALUE

Upon success, the acl_copy_int function returns a pointer that references the ACL in working storage. On error, a value of (acl_t)NULL is returned, and errno is set appropriately.

ERRORS

If any of the following conditions occur, the acl_copy_int function returns a value of (acl_t)NULL and sets errno to the corresponding value:
[EINVAL]
The buffer pointed to by the argument buf_p does not contain a valid external form ACL.
[ENOMEM]
The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.

STANDARDS

IEEE Std 1003.1e draft 17 (\(lqPOSIX.1e\(rq, abandoned)
